Choosing a storage unit can get confusing once you start comparing indoor and outdoor units, drive-up spaces, climate control, lockers, and specialty storage. The right option usually depends on what you are storing, how often you need access, how long your belongings will be there, and whether they need protection from changing temperatures or humidity.

We know the features, benefits, and drawbacks of each, and this guide will walk you through how the main types of storage units compare, what they are best suited for, and what to consider before signing a rental agreement.

The four main types of storage units are indoor units, drive-up units, climate-controlled units, and storage lockers. Many facilities offer more than one type, although the sizes, features, and access arrangements vary by location.
Before comparing facilities, it may help to review how to rent a storage unit and what is normally included in the rental process.
Indoor storage units are located inside a larger building rather than opening directly onto a parking lot. Reaching the unit may involve entering through a secured door and using a hallway, elevator, or loading area.
Because the units are inside, belongings have another layer of protection from rain, snow, wind, dust, and outdoor temperature changes. Many indoor facilities also use keypad access, security cameras, and individually alarmed units, although security features differ from one property to another.
"Vehicle storage… can also provide an alternative when a homeowners association does not allow RVs, boats, trailers, or extra vehicles to remain in a driveway."
Indoor storage can work well for boxes, household goods, furniture, clothing, and personal belongings. It may also be more comfortable when you expect to visit the unit regularly or plan to keep things in storage for several months.
Keep in mind that where the unit sits inside the building can make a noticeable difference on moving day. A ground-floor unit near the entrance may be only a short walk from the truck, while an upper-floor space could involve elevators and longer hallways. Many facilities have carts or dollies available, though it helps to find out what will be there before you arrive.
A drive-up unit opens directly onto the facility’s driveway, so a car, van, or moving truck can usually park close to the door. That shorter path can be especially helpful when you are storing appliances, furniture, tools, or a large number of boxes.
Drive-up facilities often have gated entry, cameras, lighting, and locks on the individual units. Since these spaces open outdoors, take a moment to look at the door, floor, and surrounding pavement. Signs of past water entry, gaps around the door, or drainage problems may be worth asking about before you rent.
Climate-controlled units are designed to keep conditions more consistent than a standard storage space. They are usually inside an enclosed building and often cost a little more because the facility is heating, cooling, or otherwise managing the indoor environment.
The added protection can matter for belongings that may warp, crack, fade, corrode, or develop mold when exposed to heat, cold, or moisture. Common examples include:
Be aware that the meaning of “climate-controlled” can vary between facilities. In some places, it refers only to temperature, while others also monitor humidity. A quick question about the temperature range and humidity controls can give you a clearer idea of what you are paying for.
A standard unit may be perfectly suitable for sturdy items such as plastic totes, metal tools, patio furniture, or belongings stored for a short time. The added cost of climate control tends to make more sense for things that would be expensive, difficult, or impossible to replace.
Storage lockers are smaller than standard storage units and may be only a few feet wide and deep. Some are also shorter than full room height, with another locker stacked above or below them.
Their smaller size usually makes them one of the least expensive storage options. They can be useful for:
A locker may be enough when you need to clear a closet, store a few items during a temporary move, or keep dorm-room belongings over the summer.
The smaller size makes storage lockers affordable, but it also limits what can fit inside. Most will not hold furniture, appliances, or oversized boxes, and stacked lockers may require a ladder or rolling staircase. Be sure to look at the height as well as the floor dimensions, since a 5-by-5 locker may be much shorter than a regular 5-by-5 unit.
Some belongings need more than a standard household storage unit. If you’re planning on storing a car, you’ll need a unit with enough room and suitable access. Wine, business inventory, and other specialty items also need particular temperatures, security features, or loading arrangements.
Vehicle storage usually comes in three forms: an uncovered outdoor space, a covered space, or a fully enclosed indoor unit.
Vehicle storage may be useful during a long trip, military deployment, home renovation, or a seasonal period when a boat or RV is not in use. It can also provide an alternative when a homeowners association does not allow RVs, boats, trailers, or extra vehicles to remain in a driveway.
When choosing a vehicle storage space, make sure you account for more than the vehicle’s basic length and width. For RVs and trailers, factor in mirrors, roof-mounted equipment, turning room, and the extra space needed to back in safely.
"A nearby facility can be convenient, but the closest option is not always the best value. If you rarely expect to visit, a facility farther outside the city may offer more space for less money."
Also keep in mind that each facility sets its own rules for vehicle storage. Some ask for current registration and insurance, while others have requirements related to fuel levels, vehicle condition, or maintenance on the property.
Wine storage provides more precise temperature and humidity control than a typical household unit. Keeping conditions steady can help protect the cork and preserve the wine’s quality over time.
Purpose-built wine storage may include individual lockers, bottle racks, backup power, restricted access, and monitoring systems. These spaces are most common in larger cities and wine-producing areas, so they may not be available at every self-storage facility.
Other belongings that may benefit from specialized temperature or humidity control include:
A regular climate-controlled unit may offer enough protection for many household valuables. Fine wine, archival materials, rare art, and other highly sensitive collections may need a facility with tighter environmental controls. The actual temperature and humidity range will tell you more than the name of the storage option.
Business storage gives companies a place to keep inventory, tools, records, supplies, or equipment when there is not enough room at the office, storefront, or home. It can be useful for several types of businesses, including:
Businesses that handle large or frequent shipments may need oversized doors, higher ceilings, electrical service, or loading docks.
For businesses that visit the unit often, access can matter as much as size. A ground-floor or drive-up space can make regular pickups easier, and some facilities offer extended hours or accept deliveries. Those services are not available everywhere, so they are worth asking about when comparing locations.
Before renting, check whether the agreement allows commercial use and whether there are limits on deliveries, employees, customer visits, electricity, or work performed inside the unit.
The right storage unit size depends on the amount and shape of what you are storing. A 5-by-5 unit may hold boxes and small furniture, while a 10-by-20 unit can often accommodate the contents of a multi-bedroom home.
Storage Unit Sizes and Their Equivalent Space
| Size | Dimensions | Best For | Equivalent Space |
|---|---|---|---|
| Small | 5 x 5 or 5 x 10 ft. |
| Closet to small bedroom |
| Medium | 5 x 15, 10 x 10, or 10 x 15 ft. |
| Small bedroom to half a garage |
| Large | 10 x 20, 10 x 25, or 10 x 30 ft. |
| One- to two-car garage |
Keep in mind that two units with the same floor dimensions may not hold the same amount if their ceiling heights or door openings differ. A simple list of your largest furniture pieces, appliances, and estimated number of boxes can make the facility’s size guide easier to use.

Choosing a storage unit comes down to four questions: What are you storing, how long will it be there, how often will you need access, and what fits your budget?
Those answers can help narrow down the type, size, location, and features that matter most. Before signing a lease, these questions to ask a self-storage facility can help you compare the details.
The belongings going into storage are the best place to start when deciding on a unit because they determine how much space and protection you need.
Be mindful that fragile and unusually shaped belongings often use more space than expected because they cannot always be stacked. Taking furniture apart may help, but wood and upholstered pieces still benefit from a little breathing room and enough space for protective covers.
HireAHelper’s guide to storing furniture in a storage unit explains how to protect larger pieces during storage.
How long you need storage can change which features matter most. A short stay may only require convenience and easy access, while longer storage may make climate control, security, pest control, and insurance more important. It also helps to think about whether you will need to remove and replace items during the rental period, such as seasonal decor, sports gear, or business inventory.
Most storage rentals are month-to-month, but the price advertised at move-in may be temporary. Before signing, look for details about future rate changes and how much notice the facility requires when you are ready to leave.
A nearby facility can be convenient, but the closest option is not always the best value. If you rarely expect to visit, a facility farther outside the city may offer more space for less money. Regular access may make a closer location worth the extra cost.
Access hours differ from one facility to another as well. Some allow entry around the clock, while others open the gates only during set daytime or evening hours. The office may keep a separate schedule, so someone may not be available to help even when you can still enter the property.
Other details to compare include:
No storage facility can remove every risk, but a clean, well-maintained property with controlled access may offer more reassurance. Learn more about whether storage units are safe and which self-storage security features are worth looking for.
The monthly price reflects more than the size of the unit. Location, local demand, climate control, indoor or ground-floor access, and added security features can all affect what you pay.
Storage options often fall into these general price ranges:
Recent national storage data puts the average price of a 10-by-10 non-climate-controlled unit at about $119 per month, with climate-controlled units averaging about $134. Actual prices vary significantly by city, and your rate may also change after an introductory offer.
Promotional rates can make one facility look much less expensive at first. To compare the real cost, include the regular monthly rate along with administration fees, locks, insurance, taxes, and any required notice period. A discounted first month may not save much if the price rises soon afterward.
Storage can be useful when closing dates do not line up, renovations are unfinished, or you would rather unpack the new home gradually. Organizing the unit around what you will need first can save you from shifting boxes around every time you visit.
Whether you are putting belongings into storage or bringing them back home, HireAHelper makes it easy to compare local moving crews that can help load or unload your truck or storage unit.
